سنن النسائي

It was narrated that 'Aishah said: "I noticed the Messenger of Allah (ﷺ) was missing one night, and I found him when he was prostrating with his feet held upright, and he was saying: 'Allahumma, inni a'udhu biridaka min sakhatik, wa bimu'afatika min 'uqubatik, wa bika minka la uhsi thana'an 'alaika anta kama athnaita 'ala nafsik (O Allah, I seek refuge with Your pleasure from Your wrath, in Your forgiveness from Your punishment and in You from You. I cannot praise You enough, You are as You have praised Yourself.)"
